Be it known that I, JOHN CLAY, a subject of the King of England, residing at 64 Mersey road, Rock Ferry, in the county of Chester, England, have invented new and useful Improvements in or Connected with the Production of Combustible Mixtures, of which the following is a specification.

This invention has reference to the production and supply of combustible Huid to internal-combustion oil or spirit engines, the combustible uid consisting of atomized and Vaporized oil or spirit and air; and one of the chief objects and effects is to produce and supply such iiuid that it will be practically permanent, so that it can be used at any time after having been produced and at any moment as and when required, and enable engines to be started, operated, controlled, and maneuver-ed with the same facilities practically as a steam or like engine.

According to this invention air and oil or spirit are drawn together into a chamber by creating a partial vacuum in that chamber by a pump and atomizing them in that chamber, and the mixture after being drawn through the chamber and the pump-cylinder is forced by this pump-piston into a heater and thence into a storage-reservoir, from which it will be supplied to `the engine as and when required.

The machinery isillustrated in the annexed drawings, and the invention will be further described by their aid. Y

In the drawings, Figure 1 is an elevation, partly in section. Fig. 2 is a plan, partly in section; and Fig. 3, an end View, partly in section, showing the atomizing and mixturesupplying' apparatus; and Fig. 4 is a plan, partly in section, showing this atomizing and supplying apparatus in conjunction with the mixture-heati ng apparatus.

Referring to the drawings, 1 is a box or chamber in which the partial vacuum is made and the oil or spirit is atomized with air and the mixture made.

2 represents an ordinary piston-pump, of which 3 is the piston, and 4 represents an ordinary-piston-valve for controlling the inlet and outlet of the mixture into and out of the cylinder 2, while 5 represents an oil or spirit pump-of ordinary construction, the plunger of which is formed by the extended end of the rod 6 of the Valve-pistons 7.

The chamber 1 communicates with the ports 8 of the cylinder by a passage 9 and thence ternal pipes 12, fastened in vdiaphragms 13, to-

and through which pipes hot gases--say the waste hot gases of the oil-engine or other heating-gases-pass by a pipe 14, while the waste gases pass away from the opposite end by a pipe 15.

Oil is supplied to the atomizers 17 in the chamber 1 from the pump 6 through the pipe 18, branches of which enter the upright airinlet branches 19 of the atomizers 17. The discharge ends of these atomizers are exactly opposite each other in the box 1, and the two streams of atomized oil and the air mixed with it meet one another, and thereby produce an impactV and cause the particles of oil to be thoroughly broken up by the impact and mixed thoroughly with the air, so as to form a homogeneous mixture.

According to the capacity of the pump 2 and the Velocity at which it works so will be the quantity of air supplied, and this,of course, will be known, and as the oil-pump 6 is worked the same number of strokes as the cylinder 2 and the piston-valve (all of which may be Worked from a moving part of the main engine) the amount and proportion of air and oil supplied to the atomizer will be proportional and measured, so that a constant and uniform mixture of the required proportion of air and oil is had at all times. This mixture passes from the pump to the heater l1 by the pipe 10 and in passing over the pipes 12 said sprayer;` vand a surface heater connected with said distribution-valve delivery; substantially as set forth.

2. In apparatus for producing combustible mixture of oil or spirit and air for internalcombustion engines, the combination of an exhausting-cylinder with the distributionvalve; a chamber adapted to be exhausted in communication with the distribution-valve cylinder; a plurality of oil-sprayers having their deliveries within said chamber, and disposed directly opposite to and in line with each other; oil and air conduits external to said chamber, and communicating with the said sprayers, to cause the streams to strike each other; substantially as setforth.

3. In apparatus for producing combustible mixture of oil or spirit and air for internalcombustion engines,"thecombination of an exhausting-oylinder 2 with piston 3; a distribution-valve 1; a closed chamber 1, communicating with said distribution-valve and exhausting-cylinder; sprayers 17 fixed in said chamber; anoil-pump 5 connected with a moving part of the exhausting-engine; an air-inlet 19 on the sprayers 17, and communicating with the atmosphere; and an oil-pipe 18 communicating between the air-inlet branches 19, and the pump 5; as set forth.

In testimony whereof Ihave signed my name to this specification in the presence of two subscribing witnesses.
